Whether you're competing in the TCR or your local 100k gravel fondo CdA gains in the frame benefits every rider, though I share the sentiment that "aero" on Chinertown is generally more of an aesthetic sensibility than the end result of rigorous R&D.

Just for fun, do you think this bike is more or less aero than a naked frame?


How about this one? Faster with or without the bottle?



Fender mounts, unused, are invisible to the wind and add a great deal of utility to the frame without adding any meaningful weight. Downtube mounts and frame storage allow for additional water carry behind the saddle — an aero gain — while preserving secure storage space for tools, tent poles, or yet more water. Because they effectively act as frame fairings or help stop airflow detaching, in many cases a bike equipped for bikepacking/ultraracing is _faster_ than one without.

Agree that it looks like a G3 - they're likely just quoting clearance with the ISO standard of 4mm for road applications rather than the off-road standard of 6mm.

Can someone stuff a 55-56mm WAM tire in the front and let us know if it clears? If this can take a 2.2 in the fork it's probably the best option out there for people looking for a more aggressive Seigla

I don't understand how this is a clone any more than every single round tube alu era bike was a clone of, idk, a CAAD3? The Aethos looks like every non-aero frame of the last 30 years and vice versa!

It's fun to have a light, snappy bike that fills you with nostalgia for the period when you first started riding without all the downsides bikes from that era possess. Having a race bike with all the aero fixings is great for days where you need to go fast, but for the vast majority of rides -- even for very serious, competitive athletes -- marginal gains don't matter. On those days having a bike that makes you smile is worth infinitely more than 10w in a Tour test.

In my infinite (lack of) wisdom, I did not pester Kitty about adding the plate they are shipping with the new HB052 to actually _mount_ these things to. Does anyone have a suggestion for brackets that might work and attach to the 25mm bolt spacing stackers that have come with the TT912 and TT119 previously? It looks closest to the Vision TFE/TFA extension adapters, but I don't believe those have the appropriate bolt spacing.

Just saw a build thread on WW with weights listed for a sz 54 v2 in glossy black.

Frame was 927 including bottle bolts and both hangers, 476g for the fork. These frames really aren't far off…
